There must be a way for me to iterate the solve block of the attached worksheet throug a "range variable" of the angles:
Iteration would mean to me that the calculated values of one step are taken as input for the next one. Do you real mean that kind of procedure. It doesn't seem so as otherwise the two angles would have to be output variables.
Or do you just want your 6x1 vectors of forces calculated for a couple of alpha/beta combinations (and if yes - which?). That is just cycle through a range of angles.
Beta could be expressed using Alpha so in reality it is only a sollution for one variable that i need
So why don't you do that in your sheet and show how?
I would be able to do it if i where trying to iterate throug a range of a normal variable like for instance F.AX or similar,
??? Not sure why F.AX is more "normal" than one of your angles.
Anyway, it seems to me that for whatever you are finally after you should make your angles parameters of the function.
Look if the attached would be a step in the right direction
Maybe its also interesting to know that your system can be solved symbolically and the results may be used for future calculations avoiding the solve block and the guess values:
